By the numbers, the .260 is the best round. Fits in a standard short action rifle, which the Swede doesn't. Shoots flat, starts with less energy than 7mm-08 so it has even less recoil, but it retains energy better, so .260 hits the target just as hard as the 7mm out at rifle distances.
However, 7mm-08 is the easiest to find on a gun store shelf if you don't reload, or want the option of buying a box of hunting ammo. And it might be easier to find a rifle chambered in the Swede than .260.
The real bummer about the Swede is that, if you buy it in a modern American bolt rifle, it's usually in a mismatched long action (.30-06 length). For some reason, that doesn't sit well with me.
